Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a screen interactive program testing method, and more particularly to a screen interactive program testing method for automatically testing a screen interactive program such as a text editor.

Conventional technology A screen interactive program such as a text editor, in which data and commands are entered by keyboard operations such as a sentence J: displayed on a CRT screen, and sentences are changed, inserted, deleted, etc. in an interactive manner. .

By the way, data and commands entered from the keyboard of a terminal device are converted into a predetermined format, and control characters and signals are added to the data stream for the general-purpose line, and then sent to the central processing unit via the general-purpose line. It is transmitted to the CPU. Thereafter, it is processed by the screen interactive program in the CPU, and the response data of this program is supplied to the terminal device through a general-purpose line, and a screen corresponding to the input data, command, and response data is displayed on the CRT.

Problems to be Solved by the Invention When the screen interactive program described above is created, it is necessary to test whether the program operates normally without errors.

However, in order to test screen-interactive programs, test data traditionally had to be created in the form of data streams for general-purpose lines.
Creating test data in data stream format including synchronization signals etc. requires a great deal of effort. For this reason, in reality, tests are performed by running the screen interactive program to be tested using keyboard input from a terminal device and viewing the results on a CRT screen, which increases test time due to keyboard input. There was a problem in that a reliable test could not be performed due to incorrect keyboard operations, oversight of the CRT screen, etc.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a test method for a screen interactive program that solves the above problems by testing the screen interactive program using test data in the data format of a terminal device. Ru.

Means for Solving the Problems In the present invention, a plurality of test data created in a terminal device data format are stored. The data on the display screen is changed in accordance with the sequentially extracted data, and the changed screen data is converted into a data stream format and supplied to the screen interactive program.

The response data stream of this program is converted into response data in the data format of the terminal device and stored, and the data on the display screen is changed in accordance with the response data to prepare for a test using the next test data.

In the present invention, a data stream is generated using pre-stored test data in the data format of the terminal device to test a screen interactive program, and the response data stream output by this program is generated in accordance with the data format of the terminal device. Since it is converted to response data and stored, test data creation is easy, test time is shortened due to automatic testing, and results can be confirmed reliably by outputting stored response data. It will be done.

Embodiment FIG. 1 shows the operating environment of the system of the present invention. In the figure, test data storage means 10 stores in advance a plurality of test data for screen interactive programs. This test data is similar to data and commands entered on an actual keyboard. For example, the second part of the CRT screen
To write the character rABj in the third column of the field and write the character rA[3cJ in the first column of the fourth field, write the data "2゜3,AS,4.1.ABCJ" in the parameter format. In addition, test data for specifying and deleting an arbitrary character, test data for specifying an arbitrary position and inserting an arbitrary character, etc. are stored in the test data storage means 1o. remembered.

The image data generating means 11 performs processing as shown in FIG. In FIG. 2, first, a single D1-data is read out from the test data storage means 10 (step 20).
>. The screen data generation hand g111 stores currently displayed screen data, which is screen data of all fields displayed on the CRT screen.

For example, as shown in FIG. 3 (A>), when there is a display in each of the seventh field 40a to fourth field 40d on the CRT screen 4°,
The screen data for each field is stored as double-sided data during display.

In step 21, the read test data is analyzed, and the currently displayed screen data is rewritten in accordance with this test data. For example, if the test data is data r2.3. AB, 4゜1, AB (, J) If the input command consists of the input command, the screen data of the second field of the currently displayed screen data is "12△B", and the fourth field The screen data of is set as rABCJ.After this, the screen data of the field that has been changed in the screen data being displayed is extracted field by field (step 22).In other words, the screen data as shown in FIG. 3(B) is extracted. Screen data r1 of the second and fourth fields of the middle screen data
2ABJ and rABCJ are extracted. The screen data of this extracted field is supplied to the line simulator 12.

(Step 23).

The line simulating means 12 shown in FIG. 1 converts the extracted field unit screen data supplied from the screen data generating means 11 into a data stream format of the line connecting the actual keyboard and the CPU. Through this conversion, a data stream is obtained in which a synchronization signal in a predetermined format is added to two numerical screen data in a predetermined format indicating an extraction field number and a control statement 7 indicating a change in screen data.

The data stream is supplied to the screen interactive program 13 to be tested, processed by the screen interactive program 13, and the response data stream output by the screen interactive program 13 is supplied again to the line simulating means 12. The line simulating means 12 converts this response data stream back into the data format for the actual keyboard, and supplies the obtained response data to the screen data generating means 11.

Returning to FIG. 2, after receiving the response data by the line simulating means 12 in step 24, this response data is written and stored in the response data storage means 14 (step 25). Furthermore, line simulation 1-method 1
2 rewrites the displayed double-sided data in accordance with the response data (step 26). As a result, preparations are made for the next D1-data. Of course, if the response data does not instruct a change in the display screen, the double-sided data during display is not rewritten. After that, in step 27, it is determined whether all the test data in the test data storage means 10 has been read out. If there is still some remaining, the process moves to step 20 and steps 20 to 27 are repeated, and if not, the process shown in the second figure is performed. end.

In FIG. 1, screen image data generation means 1
5 merges the response data in the response data storage means 14 and the test data in the test data storage means 10 to generate screen image data to be displayed on the CRT screen;
This screen image data is output by the screen image data output means 16 in the same format as the CR7 screen.

The above-mentioned screen image data can be generated arbitrarily at J3 after the processing shown in the second diagram is completed or during the processing.

By the way, as the test data storage means 10 and the response data storage means 14, for example, a 11 disk device is used, and the screen data generation means 111 line simulation means 1 to 12. Each of the screen image data generation means 15 is a program, for example, and is processed by a CPU on which a screen interactive program to be tested is executed, and the screen image data output means 16 is, for example, a printer or a CRT.

In this way, the test data is created in the terminal neck data format, so it is easy to create, and because one test is automatically performed using a plurality of stored test data, the test time is shortened.

In addition, since the stored response data is merged with the test data and output as a screen image, the MiA of the test results is
can be done very easily and reliably.

Note that the screen image generating means 15. Response data storage means 1 is provided in Party A without providing screen image output means 16.
It is also possible to simply output the response data stored in No. 4, and the present invention is not limited to the above embodiment.

Effects of the Invention As mentioned above, in the method of the present invention, the test data is in the asthmatic data format, so it is easy to create Days 1 to 4, and the test is performed automatically, so the test time is shortened. Its features include the ability to reliably confirm test results by outputting stored response data.
